Problems solved by technology

The display panel realizes color or black-and-white display based on the upper and lower polarizers 10 whose absorption axes cross vertically. In view of the structure of the display panel, the double-layer polarizer 10 usually makes the light transmittance less than 43%, and the setting of the color filter 13 will Make the light transmittance less than 30%, so that the overall light transmittance of the display panel is greatly reduced when realizing transparent display
[0004] The traditional transparent display panel achieves the effect of increasing transparency by adjusting the haze of the polarizer, reducing the thickness of the color film glue on the color film substrate, etc., but the transmittance is still lower than 15%, which greatly improves the transparent display effect.

Embodiment 1

[0030] This embodiment provides a display panel, such as figure 2 As shown, it includes a plurality of sub-pixels 1, each sub-pixel 1 includes a light-transmitting area 11 and a display area 12, the light-transmitting area 11 is used to transmit ambient light, and the display area 12 is used to display images under the action of an electric field.

[0031] In the display panel, each sub-pixel 1 is partitioned, and the light-transmitting area 11 transmits ambient light, and the display area 12 displays an image, thereby not only realizing the transparent display of the display panel, but also enabling the display panel to display in a transparent manner. When the light transmittance is greatly improved, the transparency effect of the display panel is improved, and the transparent display effect of the display panel is further improved.

[0032] In this embodiment, the display panel includes a liquid crystal cell 4 formed by pairing an array substrate 2 and a transparent cover ...

Embodiment 2

[0047] This embodiment provides a display panel. The difference from Embodiment 1 is that the display panel in this embodiment is ADS (Advanced Super Dimension Switch, advanced super dimension field switching technology) display mode or H-ADS (High Aperture Ratio Advanced Super Dimension Switch, advanced ultra-dimensional field switching technology with high aperture ratio) display mode. Since the ADS or H-ADS type display panel is turned on, the area where no image is displayed is in a normally black state (that is, a normally dark state), and the normally black state makes the area where no image is displayed cannot pass through ambient light, that is, transparent display cannot be achieved. Therefore, in order to realize the transparent display of the display panel, it is necessary to make the light-transmitting area pass through ambient light, so an electric field must be formed in the light-transmitting area of ​​the display panel, that is, electrodes must be installed in ...

Embodiment 3

[0052] This embodiment provides a display panel. The difference from Embodiment 1-2 is that the display panel is not provided with a light splitting film, but is provided with a color filter layer, and the color filter layer is provided on the light incident side or the light exit side of the liquid crystal cell. The color film layer includes a red color film, a green color film and a blue color film, and the red color film, the green color film and the blue color film are correspondingly distributed in the display area of ​​each sub-pixel. Among them, the color film layer adopts traditional color film glue.

[0053] By correspondingly distributing the color filter layer in the display area of ​​each sub-pixel, not only can the color and black and white display of the image in each sub-pixel display area be realized, but also the light-transmitting area of ​​each sub-pixel can normally transmit ambient light, and the light transmission The transmittance of ambient light in the...

Abstract

The invention provides a display panel, a driving method thereof, and a display device. The display panel comprises a plurality of sub-pixels; each sub-pixel comprises a light transmission area for transmission of ambient light and a display area for displaying images under the action of an electric field. As the sub-pixels are partitioned, ambient light penetrate the light transmission areas, and the images are displayed by the display areas, not only is transparent display of the display panel realized, but also the light transmittance of the display panel during transparent display is greatly improved, the transparency effect of the display panel is improved, and the transparent display effect of the display panel is further improved.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display panel, a driving method thereof, and a display device. Background technique [0002] As a new type of application that has emerged in recent years, transparent display panels have attracted people's attention. This technology has greatly expanded the scenarios and scope of display applications, and has also provided convenience for people's lives. [0003] However, the existing liquid crystal transparent display technologies are all based on traditional liquid crystal display panels. Such as figure 1 Shown is a traditional liquid crystal transparent display panel, which is formed by combining an array substrate 2 and a color filter substrate 14 . The display panel realizes color or black-and-white display based on the upper and lower polarizers 10 whose absorption axes cross vertically. In view of the structure of the display panel, the double-layer pola...
